The Read and Write speeds would be faster or slower than the USB-3 hardware on MacBooks?

Speed of memory itself. I have an unusable 64 gb drive. Too slow. Patriot fast on usb2 or 3

It will read all cards on the USB 3 channel. The problem will be the cards themselves. Even the fastest cards today 60MB/s to 80MB/s are still MUCH slower than USB 2.0 speed with is 480MB/s. The only devices that will perform significantly better on USB 3 over USB 2 are external hard drives or SSD drives.

The card I had worked perfectly with my Macbook air (late 2011), and was way faster, 1GB would take about 30 to 40 seconds to copy. I sent mine for replacement after 6 months of usage because it did not work on my new MBP (late 2013). I am supposed to get the new one shortly.

You should have no problem. My mac has USB 2.0 and this drive supports USB 2.0 or USB 3.0 natively. The only difference you will see is the data transfer speed, and honestly, even with USB 2.0 interface, the data transfer is pretty fast.

Well, the core i3 is much faster in performance. I mainly use my macbook to surf the web, take notes for class, and do some note taking. I also use this macbook to write my books that I plan to publish.

This thing is very fast never had a read issue. I think it would be more dependent on the speed class of the SD card. The USB speed on this thing blows my mind!

as long as the mac device has a usb option. what kind of device are you trying to use it for?

According to both the online documentation and the documents that came with the drive, the answer is yes. I can also offer my own experience as I've been using these drives with both my older iMac w/USB 2.0 interface and my new iMac w/USB 3.0 interface and both work as expected. USB 2.0 speeds are MUCH slower than USB 3.0 speeds, so expect that your throughput will be lower than the max throughput indicated on the docs; plugged into a USB 2.0 slot, the drive will operate at USB 2.0 speeds. I hope that helps! Let me know if you have other questions.

No. Unless the USB device works on USB 2.0. It won't be as fast as with USB 3. I agree with Robert.

I use a 16 GB tab on a mac laptop, USB2, OSX 109.3. It's fast enough for me. I mostly store very small documents on it. i tried a 947 MB file; took 2 minutes. a file speed tester a tried yielded speeds all over the place: write 5.5 to 9.6 MB; read 16.1 to 34.9 MB.if you want large files to transfer fast, try a Patriot Magnum. Mine is USB2; it's honkin' big, but i copied the same file in 30 seconds.

Summary: all functional tests were fine but no speed tests. Used it with a Samsung 840 Pro SSD, 256GB. Tried it first on a Windows 7 machine to delete the partitions. Moved it to an iMac with Mavericks and installed OSX to run externally on the drive. The machine boots and loads software much faster through the external USB port with this case/drive than from the internal 7200 RPM drive. While a SSD is faster than the hard drive, the internal SATA port is much faster than USB3. It comes with a Y cable, one for the USB signal connection and a second thinner cable for extra power. The power cable is not needed with the SSD and I suspect it would not be needed with one of the slower 2.5" hard drives. Summary: all functional tests were fine but no speed tests.

The short answer is no. Your speed will most definitely be limited by the slow 5400rpm disk. It will not take full advantage of the Thunderbolt or USB 3.0 bandwidth. I'll be getting a Thunderbolt drive with SSD.

The Write speed was between 9.83 MB/s and 14.43 MB/sThe Read speed was between 64 MB/s and 78 MB/sI have the 16 gb and I used usbflashspeed for benchmark

I plugged in a crappy USB 2.0 key to test this - an old Verbatim that I would swear is slower than a floppy drive. It didn't slow down the read/writes on my super speedy USB3 Patriot Magnum at all. So, no, USB 2 devices won't slow down USB 3 devices.

Yes. I have it connected to my MacPro via FW800, but its fastest speed will be utilized with USB 3.

I'm getting just under 130MB/s read and write. It took under 2 hours to copy some files (around a TB) that took seven hours under USB 2.0.

Yes. If using USB 3.0 you should use mountain lion due to the apple driver improvements in 10.8.2
